New research shows technology might be more ageing than the sun

Since Apple added a front-facing camera to its iPhone 4 in 2010, we've become obsessed with taking and sharing selfies. But could this very modern habit be taking its toll on our skin? We spoke to Lesley Reynolds of the Harley Street Skin Clinic to find out more about the impact of selfies on our skin...

Can the light from phones really affect our skin?

"The blue light emitted from our smartphones and computers is known as high-energy visible light, (HEV). Research is still ongoing but scientists have said this form of light can actually penetrate the skin more deeply than UV rays emitted by the sun. Studies also suggest HEV light can prevent skin from healing as well as accelerate the ageing process. It can also affect circadian rhythms by suppressing the evening rise of melatonin. If our melatonin levels drop it disrupts sleep, and as we know a good night's sleep is important as this is when the body and skin repairs itself. HEV light can also potentially damage the cells in the eyes, increasing the possibility of future eye disease," says Lesley.

How does blue light compare to sun damage?

"HEV light research is still in the development stages, but what has become evident to scientists is that this light penetrates the skin more deeply than UV rays, and studies on the way HEV impacts DNA, makes us believe that it could accelerate skin changes commonly associated with sun damage."

Even without concrete answers about the extent of this damage, it's pretty terrifying, considering how long we've gone without knowing this and subsequently taking the opportunity to protect ourselves.

Are people who take selfies more at risk of skin damage?

"We know that there are three main factors that age the skin – sun damage, pollution and HEV light, so yes taking lots of selfies can cause skin damage, and even accelerate ageing, especially if, as research suggests, it can infiltrate the skin more deeply. This damage can manifest itself as hyper pigmentation, enlarge pores, and inflammation. But worryingly, research suggests that HEV is a bit of a silent threat as most of the damage is not visible to the human eye, but under the skin's surface."
